Ball Wall Game

This repository contains the code for Ball Wall, a simple game built using an Arduino, an OLED display, and button inputs. The game allows the player to move a ball within a bounded area on the OLED screen, controlled by directional buttons. This project is a fun way to learn about graphical rendering, button inputs, and basic game mechanics on microcontrollers.

Features

• Displays a movable ball on a 128x64 OLED screen.
• Uses directional buttons to control the ball's movement (Up, Down, Left, Right).
• Includes boundary checks to restrict the ball's movement within a predefined area.

---

Components

1. Arduino Board
   Compatible with Arduino Uno, Nano, Mega, etc.

2. OLED Display
   128x64 resolution with SSD1306 driver (I2C communication).

3. Buttons (x4)
   Used for directional input (Up, Down, Left, Right).

4. Miscellaneous:

   • Breadboard
   • Jumper wires

Circuit Diagram

Connect the components as shown below:

Component	Arduino Pin
OLED SDA	A4 (I2C SDA)
OLED SCL	A5 (I2C SCL)
Right Button	D2
Left Button	D3
Up Button	D4
Down Button	D5
Power (VCC)	5V
Ground (GND)	GND

Ensure the buttons are configured with pull-up resistors or use the INPUT_PULLUP setting in the code.

Libraries Used

• U8g2 Library
  For controlling the OLED display and rendering graphics.

• Wire Library
  Built into Arduino for I2C communication.

---

Installation

1. Clone this repository:

   git clone https://github.com/yourusername/ball-wall-game.git
   cd ball-wall-game

2. Install the required libraries via Arduino IDE:

   • Open Library Manager (Sketch > Include Library > Manage Libraries...).
   • Search for "U8g2" and install the library.

3. Open the ball_wall.ino file in the Arduino IDE.

---

Usage

1. Wire the components as described in the circuit diagram.
2. Upload the code to your Arduino board.
3. Control the ball using the directional buttons:
   • Up, Down, Left, Right to move the ball.
4. The ball moves within a predefined boundary displayed on the OLED screen.

Customization

• Change boundaries: Modify the bounds[] array to adjust the allowed movement area.
• Speed adjustment: Increase or decrease the movement speed by adjusting the img[] update values in the code.
• Graphics: Replace image_Pressed_Button_13x13_bits with custom bitmap graphics for a different ball design.
